[PATCH] D24797: Only insert debug nodes after a phi if there is a valid insertion point

[Keith Walker via llvm-commits]

I believe this change is good as a general back-stop check.

I will look into whether using getFirstNonPHIOrDbg() would allow us to add debug data to a catchswitch as a separate improvement.
